| Abstract: | Objective To optimize the alcohol concentration of Guizhi Gancao Decoction extracted by semi-bionic alcoholic extraction （SBAE）. Methods Extracts were prepared by the best semi-bionic extraction technology and the best combination method. The contents of Glycyrrhetinic Acid, Cinnamic Acid, total flavones, volatile oil and dry extract in the each extract were determined. Results Comprehensive evaluation Y of 70% alcoholic SBAE extract was significantly higher than that of other alcohol concentration SBAE.
